Hey!! Finally i bought a jasjar. When i skimmed through it, i found there is an option to swap between GSM and WCDMA. I was wondering that can i use it for the telecom network aswell after changing the settings?

Vodafone provides the networks GSM 900/1800Mhz, and WCDMA 2100Ghz (also the 3G standard as used by Vodafone)....

Whereas Telecom uses CDMA EV-DO, which is different to WCDMA....

Thus, your Jasjar can switch between the vodafone networks, but not "to" Telecom's.

Just to clarify things a little, and build on jesseycys's answer (both for the OP and other interested parties),

The jasjar is a GSM/WCDMA device, and will only operate on GSM/WCDMA networks.
Vodafone operate these network types in New Zealand.

Telecom operates a CDMA1X/EVDO network, and GSM/WCDMA devices simply cannot be used, they are incompatible.

There are currently no devices on the market that will switch between Telecom and Vodafone, though there are some in existence, they need to be tested, approved and connected by Telecom to work (TNZ have had one in testing, but nothing has come to market yet).

Leave the device to use both networks or if you move out of 3G coverage it will not switch back to 2G

WCDMA is not the same as CDMA. WCDMA is also known as UMTS and it's an evolution path for GSM operators. CDMA (1xRTT and 1xEV-DO) is a different type of networks.

Believe me, the Jasjar will not work on CDMA networks.

I very much doubt that.... CDMA and WCDMA are in now way compatible and everyone seem to be confusing them lately....

U means 3G (UMTS). G means GPRS (2.5G).

U is better than G.

Maybe you don't live in a 3G (WCDMA) coverage area and the jasjar will display U

No not at all

U=UMTS (WCDMA) 3G
G=GPRS 2.5G packet switched

When the handset displays U you will be able to make video calls to other users in the 3G coverage area with 3G handsets
